• Q: How to service and repair the front lower Control Arm on 2007 Toyota Matrix?

  A: The front wheel removal should start every repair process before disconnecting both front stabilizer links on LH and RH sides through standardized maintenance procedures. Carry out front suspension arm sub-assembly lower No. 1 LH separation by unbolting the lower ball joint assembly front LH along with its two supporting nuts and repeat these steps for the RH side. You should detach the rack & pinion power steering gear assembly through the removal of four bolts after loosening the bolt shaft because the nut is non-rotatable and the suspension of the assembly will be required. You must suspend the engine before separating the front suspension crossmember sub-assembly by removing three bolts and three nuts to disconnect the transverse engine mounting insulator and engine mounting member sub-assembly center and then continuing with four additional bolt removal for the transmission jack descent and final crossmember removal. Lower No. 1 LH of the front suspension arm sub-assembly will come out by extracting two bolts and one nut. The first step involves temporarily tightening the front suspension arm sub-assembly lower No. 1 LH before lifting the front suspension crossmember sub-assembly with a transmission jack. This process requires using Special Service Tool: 09670-00010 to insert into base holes on both sides and tightening the bolts in the specified order. Reinstall the transverse engine mounting insulator along with the engine mounting member sub-assembly center before tightening three bolts and three nuts to 52 Nm (530 kgf/cm, 38 ft. lbs.). As a next step, install four bolts on the rack & pinion power steering gear assembly while tightening them to 58 Nm (591 kgf/cm, 43 ft. lbs.). Then, attach the front suspension arm sub-assembly lower No. 1 LH using two nuts and a bolt with a torque of 89 Nm (908 kgf/cm, 66 ft. lbs.). After installing the RH portion, proceed to add both the LH and RH front stabilizer link assemblies. The suspension needs stabilization by putting the front wheel on and lowering the vehicle multiple times while bouncing it. About 137 Nm (1,397 kgf/cm, 101 ft. lbs.) is needed to fully tighten two bolts and a nut on the front suspension arm sub-assembly lower No. 1 LH. The most important step is tightening the bolt because the nut cannot turn.
